Abstract: ADJUSTABLE ORIFICE FOR A SPRAYER UNIT ABSTRACT An assembly (1) for providing a number of different size orifices for a sprayer unit, such as a hand-held paint sprayer, has an orifice plate (12) with a number of orifices (17) of different diameters radially disposed near a periphery of the plate. The plate (12) has a centrally disposed pivot pin (13, 14) which is received in a complement-ary slot (15,16) in the nozzle guard (2) for the sprayer unit. The orifice plate (12) has a like number of detents (23) in the periphery thereof, and is held in place both within the slot and so as to align one of the orifices with the discharge nozzle (6) for the sprayer unit, by a clip spring (19) having angled free ends (24) respectively received in detents (23) on opposite sides of the orifice plate. Axial movement of the orifice plate is restrained by tightening the nozzle guard (2) which is received by threads (5, 51) on the sprayer unit. When a different orifice size is desired, the nozzle guard (2) is loosened, the orifice plate (12) is rotated about the pivot pin (13, 14) to position the desired orifice (17) in front of the discharge nozzle (6), and the nozzle guard (12) is again tightened.

Abstract: ABSTRACT A sound source apparatus of electronic equipment employs a frequency modulation.  Wave-form data of a fundamental wave and a modulation wave are both stored in a RAM as the 6-bit digital data.  A sine wave signal is produced  by a modulation wave frequency data and the wave-form data from the RAM,  the sine wave signal is multiplied with an amplitude data  of the modulation wave to obtain the modulation index data (J(t)).          The  frequency  data(.omega.c)  of  the  fundamental  wave  and  the modulation index data are multiplied,  and a result of the multiplication is given as a read out address of the RAM for storing the wave-form data of the fundamental wave,  thereby the read out speed of the RAM is changed.   The digital data read out from the RAM is converted as a sound signal of an analog signal by a D/A converter.   An amplitude data (A) of the fundamental wave is further pulse-width modulated,  and the digital  data from the RAM is gated by the modulated pulse, thus the output of the D/A converter is activated and, therefore, the output of the D/A converter becomes to a sound signal represented by the equation e = A sin J (t) .omega.ct.

Abstract: ABSTRACT OF THE DISCLOSURE       Purification and solubilization of proteins produced in transformant microorganisms as insoluble, biologically inactive inclusion bodies is effected by solubilizing the inclusion bodies in SDS; treating the SDS-protein solution with urea; removing the SDS and purifying the protein by chromatography on an anion-exchange resin having cationic groups attached to a polysaccharide support; and dialyzing the solution obtained from the anion-exchange resin to remove urea, thereby allowing the protein to fold into its native conformation.  The solution thus obtained can be activated by removing soluble protein aggregates via ultrafiltration or chromatography on a weak anion-exchange column.

Abstract: ABSTRACT         A toilet seat  is provided with a slide housing comprising nozzles for spraying and/or applying water and/or a disinfecting liquid.  It comprises at least one wiper for drying the surface of the seat.  The slide housing is placed over a segment of the seat, which then, while being sprayed by the nozzles, is driven in the circumferential direction by at least one electric motor.  The entire operation is started up manually by actuating the lever of the flushing water cistern,  and  subsequently  is  controlled by the  control electronics  until  the  cleaning  of  the  seat  has  been completed.  The energy is obtained by a turbine, which is mechanically  connected  to  a  low-voltage  direct-current generator, and is driven by the water filling the flushing water cistern.  The actual flushing water, therefore, flows at the normal kinetic energy into the toilet; the hydraulic resistance of the turbine is not switched on while the flushing water flows into the toilet bowl.  The device is extremely reliable, does not carry any dangerous electric voltages,  and in addition contains safety measures which prevent possible injuries, in particular of children.  It is suitable for use with new installations,  as well as for adaptation to already existing toilets.

During the absorption, most of the MgO is converted to MgSO4 and the rest is solubilized as MgSO3 and Mg(HSO3)2.  The clear solution having a pH in the range of about 3 to 5 obtained at the end of the absorption is brought to about 40°C and is treated with sulphuric acid in an amount representing at least 5% in excess of the stoichiometric requirement whereby sulphite and bisulphite of magnesium are converted to magnesium sulphate.          The magnesium sulphate obtained above can be used in a two stage addition of potassium chloride to obtain magnesium chloride, and calcined dolomite added to the remainder whereby magnesium hydroxide is precipitated and may be filtered off from the resulting CaC12 solution.  The process provides a means of removing SO2 from flue and smelter gases and at the same time produces industrially important chemical products (SO2, H2SO4, K2SO4, MgO/ CaC12).
